25% RULE. A rule governing grease trap maintenance. It requires that the depth of both bottom solids and floating oil/grease in a trap shall not equal or be greater than 25% of the total operating depth of the trap. The operating depth of a trap is the internal depth from the inlet or outlet water elevation to the bottom of the trap.

Those facilities primarily engaged in activities of preparing, serving, or otherwise making available for consumption foodstuffs and that use one or more of the following preparation activities: cooking by frying (all methods), baking (all methods), grilling, sauteing, rotisserie cooking, broiling (all methods), boiling, blanching, roasting, toasting, or poaching. Also included are infrared heating, searing, barbecuing, and any other food preparation activity that produces a hot, non-drinkable food product in or on a receptacle that requires washing. These facilities include restaurants, cafeterias, hotels, motels, hospitals, nursing homes, schools, grocery stores, prisons, jails, churches, camps, caterers, manufacturing plants, or any other sewer users as determined by the city's Water Distribution and Sewer Collection System Superintendent (WSS) who discharge applicable waste.
GREASE. Material composed primarily of fats, oil, and grease (FOG) from animal or vegetable sources. The terms fats, oil, and, grease shall be deemed as GREASE by definition. GREASE does not include petroleum based products.
GREASE TRAP. A device for separating and retaining waterborne greases and grease complexes prior to the wastewater exiting the trap and entering the sanitary sewer collection and treatment system. These devices also serve to collect settlable solids, generated by and from food preparation activities, prior to the water exiting the trap and entering the sanitary sewer collection and treatment system.
OIL/WATER SEPARATOR. An approved and industry standard system that is specifically designed and manufactured to separate oil from water. The system shall allow the oil to be collected and removed on a regular basis as to prevent it from being discharged into the wastewater collection system. Only oil/water separators manufactured for that specific operation will be approved. Adequate support literature from the manufacturer will be required so as to allow a proper review by the WSS or his or her designated official.
